The relative concentrations of volatile compounds (non-aromatic and aromatic) within a fruit or vegetable increase during maturation and ripening. The electrical conductivity of semiconductor gas detectors, based on different polymers and metal oxides, decreases on exposure to volatiles. A battery of several detectors can produce a profile that may indicate maturity or presence of some disorders. The electronic sniffer concept (40,41) has been tested on apples, blueberries, melons, and strawberries. Further research is needed to explore the selection of semiconductors and to relate the profiles to quality categories (42).
